Novel enzymes for functional carbohydrates production From scientific research to application in health food industry

This book focuses on the latest research and new techniques in the field of functional carbohydrate-related enzymes. Carbohydrates are a key form of energy for most organisms. The “good” carbohydrates generally refer to functional carbohydrates. In addition to the low or moderate energy-supplying function, they have more nutritious value than traditional carbohydrates and some of them also have health-promoting effects especially prebiotic actions. Several enzymatic methods for the synthesis of such carbohydrates have been discovered and developed in the recent decades, providing a new range of application areas for these novel enzymes.

This book addresses the classification of functional carbohydrate-related enzymes and the overall development in food enzyme in Chapter 1. Chapters 2-5 describe the isomerases or epimerases involved in the production of rare sugars, such as D-allulose, D-mannose, D-tagatose, and D-allose. While the studies of the enzymes related to fructo-oligosaccharides (FOS) and galacto-oligosaccharides (GOS) dominate the scientific literature in the field of enzymatic production of health-functional oligosaccharides, some enzymes also show promise for the emerging oligosaccharide production, which are introduced in Chapters 6-8. Chapters 9-12 summarize the new enzymatic technologies and applications in fructan- and glycan-related industries. The last Chapter gives an overall prospective on the trends of enzymatic functional carbohydrate production. This book is a valuable resource for researchers and graduate students in the fields of biotechnology, enzyme engineering, and carbohydrate production, as well as the health industry.
